ABSTRACT:
An apparatus for separating filter cake from an endless filter web, and method for using the same, for use in conjunction with a stacked plate filter system and filter web extractor. The filter cake and filter web separator apparatus includes a downwardly sloping support tray and a wedge-shaped plow blade having a resilient scrapper and suspended above, and generally parallel with, the support tray. As contaminated filter web exits a plate filter and is pulled through the separator apparatus by the filter web extractor, the resilient scrapper dislodges the filter cake from the filter web as the contaminated portion of filter web passes between the plow blade and the support plate and displaces the cake off the filter web where it falls into a suitable collection container. The filter web exits the apparatus from between the plow blade and support tray having substantially all of the filter cake removed from the filter web. In one embodiment of the invention, a suitable vacuum inlet can be disposed downstream of the plow blade to remove any residual moisture or particulate matter disposed on the filter web. Adjustment components are provided to allow height and inclination adjustment of the plow blade relative to the support tray and separation of the two components to facilitate threading of a filter web through the apparatus.
